サマリー
あらすじ・解説
The podcast explains how exercise or fasting raises epinephrine levels in the blood. Epinephrine then stimulates beta-adrenergic receptors in fat tissue, boosting the breakdown of stored triglycerides. This activation initiates a cascade, increasing cyclic AMP and activating protein kinase A. Protein kinase A then triggers hormone-sensitive lipase, leading to the breakdown of triglycerides into fatty acids and glycerol. These products are subsequently released into the bloodstream and can provide tissues with an alternative (fatty acids) source of energy to glucose.
